The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.

In centerless through feed grinding, which is a typical serial grinding process, pistons for the automotive industry, shafts, rods and also elements for the rolling bearing industry are produced. Internal cylindrical grinding: Internal cylindrical grinding is one of the most common and also most difficult grinding operations.
The lathe machine is used to remove excess material from the workpiece so that the workpiece conforms to the desired style and size. Depending on the characteristics, the following types can be divided into several types: center lathes or engine lathes, speed lathes, capstan lathes or turret lathes, tool room lathes, bench lathes, automatic lathes, special lathes, …
An automatic grinding and polishing machine is shown in Fig. 4.1. Automatic grinding methodsteps are: 1. Symmetrically load three to six mounted specimens into the specimen holder of an automatic grinding-polishing machine, with the flat sur-face of the ceramic section downward. Most manufacturers provide a
Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
